AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ELKO NV 215 PM PDT WED MAY 21 2014 .SYNOPSIS...LOW PRESSURE WILL MOVE AWAY FROM NEVADA OVER THE NEXT FEW DAYS, WITH SHOWERS AND THUNDERSTORM COVERAGE DECREASING THROUGH FRIDAY. WARMER TEMPERATURES AND PLEASANT SPRING WEATHER IS EXPECTED OVER THE MEMORIAL DAY WEEKEND. && .SHORT TERM...TONIGHT THROUGH FRIDAY. CLOSED LOW SPINNING OVER NEVADA THIS AFTERNOON, CENTERED NEAR TONOPAH. HAS BEEN AN ACTIVE CONVECTIVE DAY IN THE NORTHEAST QUADRANT OF THE CYCLONE'S CIRCULATION, WITH NUMEROUS THUNDERSTORMS PRODUCING SMALL HAIL, FREQUENT LIGHTNING, AND WINDS TO ABOUT 55 MPH. LARGE AMOUNTS OF SMALL HAIL HAVE ACCUMULATED AT TIMES, WITH AREAS OF ROTATION NOTED FROM RADAR AND STORM SPOTTERS IN THE FIELD. ONE ORGANIZED CONVECTIVE LINE WILL ROTATE WESTWARD INTO NW NEVADA THIS AFTERNOON AND EVENING, WITH STRONG STORMS AT TIMES. SPC MESOANALYSIS INDICATES CAPE OF 500-1000 J/KG IN AND NEAR HUMBOLDT COUNTY STILL, AND RESPECTABLE SHEAR, AHEAD OF THE APPROACHING LINE. CAPE IS ALREADY REGENERATING ACROSS CENTRAL NEVADA AND WHITE PINE COUNTY, WITH ADDITIONAL SHOWERS AND THUNDERSTORMS EXPECTED TO ROTATE NORTHWARD INTO NORTHERN NEVADA, SO KEPT POPS HIGH THIS EVENING AS INHERITED. CURRENTLY ONLY 40 DEGREES AT THE OFFICE, SO COLD POOL BEHIND EARLY CONVECTIVE LINE IS SIGNIFICANT, AND CAPE IS SERIOUSLY DEPLETED, SO EXPECT MUCH LESS VIGOR TO THUNDERSTORMS ACROSS CENTRAL AND NE NEVADA THROUGH THIS EVENING. EXPECT ALL CONVECTION TO DISSIPATE WITH THE LOSS OF HEATING, ACROSS ALL ZONES, BY 10 PM. AN ISOLATED SHOWER CAN'T BE RULED OUT OVERNIGHT WITHIN THE UPPER LOW'S CIRCULATION, BUT MOST ZONES WILL BE DRY. THURSDAY...CLOSED LOW SINKS SOUTHWARD AND WEAKENS, WITH ITS INFLUENCE ON NEVADA'S WEATHER LESSENING WITH TIME. GFS/NAM DEPICT ANOTHER ROUND OF INSTABILITY BY LATE MORNING, DIAGNOALLY SW-NE ACROSS NEVADA, CENTERED ON ELKO COUNTY, SO KEPT SHOWERS AND THUNDERSTORMS MENTIONED. ACTUALLY INCREASED POPS ON THE HIGHER TERRAIN OF ELKO COUNTY. AFTERNOON TEMPERATURES WILL RECEIVE QUITE A BOOST THURSDAY, AS HEIGHTS CLIMB BEHIND THE DEPARTING UPPER LOW. LESS CLOUDS, SHOWERS AND CONVECTION WILL ALSO ALLOW TEMPERATURES TO CLIMB BACK TO THE LOW TO MID 70S. FRIDAY...WARMER STILL, AS UPPER LOW WEAKENS FURTHER AND LIMPS INTO ARIZONA. HEIGHTS CLIMB SOME MORE, ALLOWING SEVERAL MORE DEGREES OF WARMING, INTO THE UPPER 70S AND LOWER 80S. INSTABILITY IS JUST ABOUT GONE BY FRIDAY, WITH ONLY MEAGER LIFTED INDEX VALUES REMAINING OVER ELKO AND WHITE PINE COUNTIES. KEPT A FEW ISOLATED THUNDERSTORMS MENTIONED FOR THESE ZONES FRIDAY AFTERNOON, BUT CERTAINLY NOT EXPECTING MUCH. TURNER .LONG TERM...FRIDAY NIGHT THROUGH NEXT WEDNESDAY. MODELS IN FAIRLY GOOD AGREEMENT WITH THE OVERALL PATTERN THROUGH THE LONG TERM PERIOD. HIGH PRESSURE BUILDS INTO THE CWA FRIDAY NIGHT AND CONTINUES OVER THE AREA THROUGH MONDAY FOR A WARMING AND DRYING TREND. A BROAD TROUGH BEGINS TO FORM OVER THE PACIFIC NORTHWEST MONDAY NIGHT FOR INCREASED CLOUDS AND DRY WARM SOUTHWESTERLY FLOW ALOFT OVER THE CWA. WINDS WILL INCREASE WITH THE APPROACHING TROUGH EARLY NEXT WEEK. TEMPERATURES WILL BE ABOUT 5 TO 10 DEGREES ABOVE NORMAL THROUGH THE PERIOD. JH && .AVIATION...MOIST AND UNSTABLE AIRMASS OVER THE REGION THIS EVENING WILL RESULT IN EARLY EVENING THUNDERSTORMS AT ALL SITES. THUNDERSTORMS WILL DEVELOP AGAIN THURSDAY AFTERNOON WITH THE BEST CHANCE AT KEKO. JH && .FIRE WEATHER...SHOWERS AND THUNDERSTORMS WILL DECREASE IN COVERAGE THROUGH FRIDAY.
